Elevating Autonomy: The Towering Triumph of ODX-6000 Inverter

The customer selected the Premium PSU solution because it was the only offering on the market that seamlessly combined high power capacity with an industrial-grade, robust, and reliable design.

In the realm of power electronics, finding DC to AC inverters with a 24Vdc input capable of exceeding 10kW is challenging. However, our ODX-6000 not only reaches that power threshold but also offers the unique capability of working in parallel.

Premium PSU’s solution not only made the project feasible but also proved instrumental in addressing unforeseen challenges.

During the implementation process, it was discovered that when the crane lowers a three-ton weight to the ground, the weight itself generates an excitation or back EMF within the motor. This causes the stored potential energy to convert into electrical energy, flowing from the motor to the inverter potentially damaging the output of the inverter. While this level behaviour was not identified in the initial specification, our diligent engineering team quickly identified the root cause.

To safeguard the equipment our engineering team recommended incorporating breaking resistors into the inverter system. These resistors dissipate the excess energy, protecting the inverters from potential damage.
